Abstract
The utility model discloses a clamping device for a sheet-like workpiece. The clamping device comprises an air cylinder, a clamp, a connecting rod and an expansion screw, wherein the clamp comprises a first clamp and a second clamp, the lower end of the expansion screw penetrates through a round pipe and then is fixedly connected with the first clamp, the lower end of the round pipe is fixedly connected with the air cylinder by the connecting rod, the air cylinder is fixedly connected with the first clamp, the second clamp is provided with a through hole matched with the round pipe, the diameter of the upper end of the expansion screw is greater than that of the round pipe, and the upper end of the expansion screw is provided with at least one opening part extending along the axial direction. By adopting the clamping device, the traditional fixing mode for clamping a sheet product is changed, and the workpiece is directly fixed on the clamp instead of being fixed on a processing board, so that the workpiece is more effectively fixed, and the phenomena of pressing to damage the workpiece and unstable size during processing can be effectively avoided.
Description
Technical field
The utility model relates to a kind of clamping device of sheet type workpiece.
Background technology
In casting industry, the aluminium silicon part thin plate clamping of processing use is a difficult problem, and solving at present the topmost method of product clamping problem has two kinds: a kind of is to increase a processing plate, and workpiece is placed wherein, is then fixed on fixture and processes; Another kind is exactly with fixture clamping, then processing after workpiece surrounding increases pressure point.But a kind of front method not only increases the difficulty that cost also increases clamping workpiece.Another kind method has also increased cost, and built on the sand, does not tackle the problem at its root.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of piece-holder difficulty that reduces, and clamping is stable, the clamping device of cost-effective sheet type workpiece.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of clamping device of sheet type workpiece, comprise cylinder, fixture, connecting rod and swell fixture, described fixture comprises the first fixture and the second fixture, described swell fixture lower end is fixedly connected with the first fixture through after a pipe, described pipe lower end is fixedly connected with cylinder by connecting rod, described cylinder is fixedly connected with the first fixture, and described the second fixture is provided with the through hole coordinating with described pipe, the diameter of described swell fixture upper end is greater than the diameter of described pipe, and described swell fixture upper end is provided with at least one peristome extending vertically simultaneously.
As the further optimization of such scheme, described swell fixture upper end has the tapering of 95～100 °.
As the further optimization of such scheme, the upper end of described swell fixture is provided with vertically extends and through two above peristome gaps in axle center, makes swell fixture have higher elasticity, more durable.
As the further optimization of such scheme, between described swell fixture bottom and pipe, be also provided with the snap device cooperatively interacting.
As the further optimization of such scheme, described swell fixture adopts elastic metallic member.
The beneficial effects of the utility model main manifestations is: changed the traditional fixed form of light sheet products clamping, by workpiece, be fixed on processing plate and change into and being directly fixed on fixture, make workpiece more effectively fixing, can effectively avoid weighing wounded and size wild effect workpiece generation in process.

The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is done to more specific detail.
Embodiment 1
As shown in Figures 3 and 4, a kind of clamping device of sheet type workpiece, comprise cylinder 5, fixture, connecting rod 6 and swell fixture 3, described fixture comprises the first fixture 8 and the second fixture 7, described swell fixture 3 lower ends are fixedly connected with the first fixture 8 after passing a pipe 4, described pipe 4 lower ends are fixedly connected with cylinder 5 by connecting rod 6, described cylinder 5 is fixedly connected with the first fixture 8, and described the second fixture 7 is provided with the through hole coordinating with described pipe 4, the diameter of described swell fixture 3 upper ends is greater than the diameter of described pipe 4, described swell fixture 3 upper ends have the tapering of 97 °, simultaneously the upper end of described swell fixture 3 is provided with and extends vertically and through two above peristome gaps in axle center.Between described swell fixture 3 bottoms and pipe 4, be also provided with the snap device cooperatively interacting, in order to avoid pipe 4 departs from swell fixture 3.For making swell fixture 3 durable in use, described swell fixture 3 adopts elastic metallic member.
Traditional clamping workpiece mechanism is locked on processing plate 1 by key screw workpiece, then be fixed on fixture 2, as shown in Figure 1 and Figure 2, before processing, processing plate 1 is fixed on fixture 2, add man-hour owing to being fixed with screw on workpiece, be easy to like this process discontinuity and cause flatness not high, size is unstable.In addition, in lock screw process, can produce aluminium bits, aluminium bits are easy to remain between processing plate 1 and workpiece, cause leaving and weighing wounded on product; And along with the increase of access times, processing plate can be out of shape gradually, causes processing work size unstable, can not effectively play a role.
The clamping device of the present embodiment, by cylinder 5, pull pipe 4 downward, reduce gradually the constraint of many swell fixtures 3, swell fixture 3 is due to the tapering of itself, upper end is thicker than lower end, therefore naturally swelling, produces the buckle power to the second fixture 7, distance between two fixtures reduces with the motion of cylinder 5, and the piece-holder between fixture is lived.This process does not produce metal fillings, avoids the workpiece that metal fillings causes to weigh wounded; Do not need to process plate, improved the production efficiency of product, save cost.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
